Definitions

  • the present invention relates to a method and related apparatus for improving Continuous Packet Connectivity in a wireless communications system according to the pre-characterizing clauses of claims 1 and 4.
  • the third generation (3G) mobile telecommunications system the Universal Mobile Telecommunications System (UMTS) has adopted a Wideband Code Division Multiple Access (WCDMA) wireless air interface access method for a cellular network.
  • WCDMA Wideband Code Division Multiple Access
  • the WCDMA method also meets all kinds of QoS (Quality of Service) requirements simultaneously, providing diverse, flexible, two-way transmission services and better communication quality to reduce transmission interruption rates.
  • QoS Quality of Service
  • a wireless communications device such as a mobile phone, to realize real-time video communications, conference calls, real-time games, online music broadcasts, and email sending/receiving.
  • these functions rely on fast, instantaneous transmission.
  • High Speed Package Access technology, which includes High Speed Downlink Package Access (HSDPA) and High Speed Uplink Package Access (HSUPA), to increase bandwidth utility rate and package data processing efficiency to improve uplink/downlink transmission rate.
  • HSPA High Speed Package Access
  • HSDPA High Speed Downlink Package Access
  • HSUPA High Speed Uplink Package Access
  • the Radio Resource Control (RRC) layer a Layer 3 protocol, is the core of communications protocols related to AS and is located in radio network controllers (RNC) of the UMTS Terrestrial Radio Access Network (UTRAN) and a user equipment (UE).
  • RRC Radio Resource Control
  • the RRC layer uses RRC messages to perform RRC procedures.
  • RRC messages are formed from many information elements (IEs) used for embedding necessary information for setting, changing, or releasing protocol entities of Layer 2 and Layer 1, thereby establishing, adjusting, or canceling information exchange channels to perform data packet transportation.
  • IEs information elements
  • CPC Continuous Packet Connectivity
  • a discontinuous transmission and discontinuous reception (DTX-DRX) operation is used to reduce power consumption when transmission between a UE and the UTRAN is decreasing.
  • the DTX-DRX operation includes discontinuous uplink transmission (uplink DTX), discontinuous uplink reception (uplink DRX) and discontinuous downlink reception (downlink DRX).
  • Uplink DTX is a mechanism where control signals are transmitted on the uplink control channels according to defined discontinuous patterns during the inactive state of corresponding uplink data channels, such as Enhanced Dedicated Transport Channel (E-DCH) or High Speed Physical Control Channel (HS-DPCCH), in order to maintain signal synchronization and power control loop with less control signaling.
  • E-DCH Enhanced Dedicated Transport Channel
  • HS-DPCCH High Speed Physical Control Channel
  • Uplink DRX is utilized for controlling the UE to transmit E-DCH in specific time interval and has to be configured with uplink DTX.
  • Downlink DRX is configured by a Radio Network Controller (RNC) and allows the UE to restrict the downlink reception times in order to reduce power consumption.
  • RNC Radio Network Controller
  • the UE is not required to receive physical downlink channels except for several specific situations. Please note that the DTX-DRX operation is enabled only when the UE is in CELL_DCH state.
  • DTX-DRX_STATUS variable Associated configurations of the DTX-DRX operation are described as follows. If the UE receives RRC CONNECTION SETUP, ACTIVE SET UPDATE, CELL UPDATE CONFIRM, or any other reconfiguration message, the UE shall determine the value for a DTX_DRX_STATUS variable that indicates a status of the DTX-DRX operation. The DTX_DRX_STATUS variable shall be set to TRUE for starting the DTX-DRX operation only when all the following conditions are met:
  • the UE shall:
  • the UE controls start or stop of the DTX-DRX operation by setting the variable DTX_DRX_STATUS to TRUE or FALSE.
  • the UE stores the content of the received IE "DTX-DRX timing information" in the variable DTX_DRX_PARAMS.
  • the variable DTX_DRX_PARAMS includes the IE "DTX-DRX timing information” and an IE “DTX-DRX information”.
  • the IE "DTX-DRX timing information” is used for indicating timing information of the DTX-DRX operation and comprises other IEs, such as an IE “CHOICE timing", an IE "DTX information”, an IE "DRX information”, and so on.
  • the UTRAN has to transmit the IE "CHOICE timing" using for selecting a timing of the DTX-DRX operation to the UE to reconfigure the timing of the DTX-DRX operation.
  • the content of the IE "CHOICE timing” comprises "new timing” or "continue”.
  • the UE if the UE confirms that the IE "DTX-DRX timing information" is included in a received reconfiguration message and the IE “CHOICE timing” is set to “new timing”, the UE stores the content of the IE "DTX-DRX timing information" in the variable DTX_DRX_PARAMS. At the same time, if the UE confirms that the IE "DTX-DRX information" is included in the received reconfiguration message, the UE also stores the content of the IE "DTX-DRX information" in the variable DTX_DRX_PARAMS.
  • the UE can use the content of the IE "DTX-DRX timing information" and does not store it in the variable DTX_DRX_PARAMS.
  • the UE only stores the IE "DTX-DRX information" in the variable DTX_DRX_PARAMS.
  • the UE starts the DTX-DRX operation only when all the above 5 conditions are met. In other words, the UE stops the DTX-DRX operation only when any one of the above 5 conditions is repealed. For example, the UE has to leave CELL_DCH state, or sets the variables HS_DSCH RECEPTION and E_DCH_TRANSMISSION to FALSE in order to stop the DTX-DRX operation after the DTX-DRX operation is enabled. In other words, the UE has to disable HSDPA and HSUPA for stopping the DTX-DRX operation. If the UE wants to keep transmission, the UE has to enter CELL_DCH state again.
  • variable DTX_DRX_PARAMS is set and the IE "DTX-DRX timing information" is received after the DTX-DRX operation is enabled. Therefore, it is impossible to stop the DTX-DRX operation by repealing the last two of the above 5 conditions.
  • the present invention aims at providing a method and related apparatus for improving a start procedure of DTX-DRX operation, for improving Continuous Packet Connectivity.
  • the claimed method of improving CPC for a UE in a wireless communications system includes receiving a reconfiguration message and starting a discontinuous transmission and discontinuous reception, abbreviated to DTX-DRX, operation when the UE meets a plurality of conditions and confirms that a specific information element, abbreviated to IE, is included in the reconfiguration message, wherein the specific IE is used for storing timing information of the DTX-DRX operation.

  • the UE when the content of the IE "CHOICE timing" is "new timing", the UE shall store the content of the IE "DTX-DRX timing information" in the variable DTX_DRX_PARAMS when not using it.
